Changelog: Cal.com v6.3 - Cal.com Agents Launch, Custom domain & SMTP configuration & more...

Cal.com agents launch

Cal.com is getting its claws into scheduling.

With Cal.com Agents, you can now ask Cal.com what’s on your agenda, reschedule meetings, add teammates to invites, and create new appointments without leaving the tools you already use. Whether you’re in Slack, Telegram, email, or your terminal with the new Cal.com CLI, Cal.com can now work more like a true scheduling sidekick.

This launch also brings a full suite of skills for builders who want to connect their own hosted agents to the Cal.com API, including projects like the OpenClaw skill. That means more ways to build, automate, and customize how scheduling works for your team.

For teams managing a high volume of coordination, support, and internal scheduling, this is a faster and more flexible way to handle the chaos. Just ask, act, and keep moving.

And because we want to see what people build with it, we’re also announcing a hackathon for those ready to get deep into the API and create their own agent-powered workflows.

Custom domain & SMTP configuration

Your brand. Your domain. Your inbox. Starting next week, you'll be able to use a custom domain for your booking links and send scheduling notifications from your own email address via SMTP, so every touchpoint with your clients stays on-brand, from the first invite to the final reminder! No more cal.com/yourteam or [email protected] in your bookers' inboxes. Just you!

Join the waitlist now to be the first to set it up when it goes live!
